Abstract/Summary

The United Kingdom Overseas Territories (UKOTs) are globally important for a high diversity of endemic and threatened plant species but are poorly represented in plant ecological literature. This lack of ecological research is compounded by a lack of funding and skills. Cost effective approaches of compiling conservation relevant information are required. Here we present the first examination of a species from the UKOTs presented within the standard framework of a Biological Flora. This framework allows a convenient way to compile ecological information and assess missing data. The account reviews all available information on Euphorbia origanoides L. (Ascension spurge) from Ascension Island (South Atlantic Ocean)relevant to understanding its ecology and conservation, including soil chemistry, climate and plant community data. E. origanoides is an endemic perennial, found in dry, lava plains of Ascension Island with soils comprised of weathered volcanic scoria. E. origanoides has suffered habitat loss through the introduction of invasive species and survival in the wild is currently under threat. We relate the information gathered for this Biological Flora to the conservation of the species in the wild and propose the framework should be used as one way of compiling information relevant for conservation managers. The framework is beneficial as it allows an evidence-based approach to conservation but also permits the prioritisation of research and can help conservation managers to meet targets for the Convention on Biological Diversity and the Global Strategy for Plant Conservation.
